Have you found any fixes for this yet? I am having the same problem with my Galaxy Watch 4 Classic. I bought it back in December 2021 and it was wonderful but after some update around April the watch stopped tracking distances when cycling or running. It does not show the route that i ran as it used to do it before the update. Also, i noticed that the watch does not acquire any sattelite in the Samsung Health app for any exercise, so this might be the problem.
